APPARATUS FOR REMOVING DIRT FROM EXCAVATIONS.

SPECIFICATION forming part of Letters Patent No. 764,201, dated July 5, 1904.

Application filed .May 25, 1903. Serial No. 158,594. (No model.)

To all whom it mug, concern:

Be it known that LIVILLIAMJ. NEWMAN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Removing Dirt from Excavations; and I do hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon, which form a part'of this specification.

This invention relates to improvements in apparatus for removing dirt from excavations and conveying the same to and delivering it to wagons or other vehicles by which it is removed; and the invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation, partially in section, of an apparatus made in accordance with my invention, showing the location thereof relatively to an excavation from which dirt is to be removed. Fig. 2 is a top plan view of the dumping-car and the hopper and supporting structure therefor, showing the car in its dumping position. Fig. 3 is a transverse section of the car, taken on line 3 3 of Fig. 4. Fig. A is a side elevation of the dumping-car. Fig. 5 is a central longitudinal section thereof. Fig. 6 is a partial plan view of said car. Fig. 7 is a transverse section of one of the deflector-bars.

As shown in the drawings, A A designate the two rails of the track, which extend from the bottom of the excavation to a point outside thereof. Said rails are supported in the bottom of the excavation on transverse sleepers A and on the sloping side of the excavation on inclined stringers A, as shown in Fig. 1. E designates a dumping-car which travels on said rails.

C designates a hopper located below the upper end of the track into which the contents of the car are dumped. The upper end of the track is arranged horizontal, or approximately so, as indicated at A, and the car is adapted to be run upon the horizontal end of the track preparatory to dumping. The upper horizontal part of the track and the hopper are supported (the latter beneath the former) on a frame structure consisting of vertical posts DD and transverse beams or girders D D D, the upper ends of the trackrails being supported on the girders D and the hopper on the girders D D The hopper is supported a sufficient distance above the ground-level to permit a wagon to drive thereunder to receive through the hopper the contents of the dumping-car, as clearly shown in Fig. 1. The hopper is provided across its top with transverse bars 0, which act to break up the load of the car when dumped into the hopper, so that said lead will adapt itself readily to the vehicle-body below. The provision of said bars also render less severe the shock of the weight of the load striking the body of the vehicle.

The dumping-car consists of an open-topped vehicle E, having a bottom wall E", side walls E and a rear wall E The bottom of the vehicle is supported on a frame consistingof longitudinal side frame members E* E and transverse and frame members E E. The side walls of the car are attached to vertical posts E, rising from the longitudinal frame members E".

. F designates a door which closes the front end of the car. Said door is arranged obliquely or inclined, and the front margins of the side walls of the car are inclined to afford seats for the door when closed. The door extends from the bottom to the top of said side walls. The door is herein shown as carried by the forward end of a swinging frame consisting of two side members, one at each side of the car, and each comprising an oblique bar F, attached at its forward end to the upper side of the door and hinged at its rear end at the rear end of the ear,and a horizontal brace bar F attached to the rear end of said bar F and at its forward end to the lower side of the door. As herein shown, said forward ends of the frame-bars F F are attached to the door by means of transverse rods f f, extendingloosely through said bars and through cleats f on the front face of said door. The rear ends of the bars F of said swinging frame are pivoted or loosely connected to a transverse rod f at the rear of the car, which is attached at its ends in lugs f, rising upwardly from rearward extensions of the frame members E of the car. The door supported in this manner on the car swings on the pivotrod f to open and close the same, the open position thereof being shown in dotted lines in Fig. 4:.

The car is supported on front and rear traction-wheels G G, respectively, which are aflixed to front and rear axles G Gr, rotatively mounted in bearings g depending from the floor-frame of the car. Said car is drawn upwardly from the excavation on the track-rails A by means of a cable H, which is trained over pulleys H H, aflixcd to the hopper and track supporting structure, and is adapted to be connected with any suitable source of power, as a motor-driven drum. The cable H is attached at its rear end to two diverging chains H H, which latter are attached to the forward ends of the bars F of the swinging door-frame. As herein shown, said rear ends of the chains are attached directly to the front ends of the frame-bars F, and the chains are joined at their forward ends to a ring to which the cable His at tached. It will be observed that by reason of the fact that the swinging frame for the door is pivoted to the car-frame at the rear lower part thereof and the further fact that the cable is attached to the door at the upper side thereof the cable when power is exerted thereon to draw the car up the incline exerts a downward pull on the door and its frame, and therefore holds said door in its lowermost or closed position.

Referring now to the devices for tilting the car to dump the contents of the same into the hopper C and from thence to a wagon below when the car reaches the upper or horizontal part of the track, these parts are made as follows: The rear axle G of the car is provided outside of each traction-wheel Gr thereof with a wheel I. Said wheels I I of the rear axle are adapted to strike when the front end of the car reaches the upper horizontal part of the track deflecting-bars J J, which are supported at their lower ends from the stringers A and at their upper ends by the posts D of the hopper and track supporting frame, the deflecting-bars J being located laterally outside of the track-rails A and parallel therewith. \Vith this construction when the car reaches the upper horizontal part of the track and the wheels I strike the deflecting-bars J the car assumes a forwardly inclined or tilted position, as shown in Fig. 1, the front end of the car being carried for wardly over the hopper C. When the car reaches this position, thedoor-frame and door are swung upwardly, owing to the location of the cable guide-pulley H, so that the contents of the tilted car are free to be discharged therefrom. After the car has been dumped and the tension on the cable is released the weight of the rear end of the car causes the wheels I thereof to travel downwardly on the rails J until the rear traction-wheels strike the rails A, the car thereby assuming a downwardly-inclined position, in which position it is carried by gravity down the inclined track to the bottom of the excavation, where it is again filled, to be thereafter drawn out of the excavation and dumped in the manner before described.

The bars J are preferably provided with metal wearingbars 7', having the form of angle-irons, which embrace the corners of the bars, as shown in Fig. 1.

By the use of the apparatus described I am enabled to quickly transfer earth from excavations to a wagon or other vehicle in which the same is to be conveyed from the excavation by means not requiring the rehandling of the earth. The apparatus is simple and inexpensive in its structure and operation and may be readily removed from place to place.

Certain of the structural details may be varied without departing from the spirit of my invention, and I do not wish to be limited to such details except as hereinafter made the subject of specific claims.

I claim as my invention- 1.
